We all want our homes to be as safe as possible. Our surge protectors defend against sudden current fluctuations. We baby-proof potential danger spots to protect our newborns and toddlers. And our smoke detectors alarm us in case of fire and smoke.

But what can we do about the air we breathe?

With the holidays and wet weather right around the corner, there's a lot we can do for those who are more sensitive to less than ideal air quality (especially our little ones!) by providing them with clean air in the home.

There are a surprising number of sources that contributes to poor indoor air quality (IAQ): allergens, dust, food and grease particles from cooking, bathroom humidity, and others. Another slightly unexpected (but perfectly logical) reason for poor air quality is the newer tightly crafted homes.

Today's newer homes are built with top-notch weatherization. In other words, because new homes are so much more sealed up than older homes, there are fewer ways for air to escape (good for your energy bills). But this also means any number of pollutants (like gas, asbestos, moisture, chemicals found in new carpet, a host of allergens, etc.) can remain trapped inside your home with nowhere to go — except our lungs.

Thankfully, there are plenty of ways to help clear the air.

To improve IAQ, make sure the air vents air to the outside. You can do this by increasing the amount of outdoor air coming indoors and circulating air in the areas like:

For superior IAQ in the home, the whole house option is the way to go. Whole house fans can replace the air in your home in minutes. Make sure you open a window, since the pressure from one of these fans can suck the soot right out of your fireplace.

One great feature of whole house fans is the amount of energy they save. By drawing in the cool evening air, you can seriously reduce your dependence on the air conditioner to cool your home during the summer.

Recovery ventilators and HEPA filtration systems are larger units, similar in size to an air conditioner. They offer constant filtration, humidity control and general ventilation, and are a great solution for homes with serious ventilation needs.

In short, venting stale indoor air to the out-of-doors will improve IAQ and help alleviate discomfort felt by those who are more sensitive.

Until next time, Happy Home Improving!
